Overview
The RS2251XTSS16 is a single-channel, 8-to-1 analog switch manufactured by Runic Technology. It operates within a supply voltage range of 2.5V to 5.5V and features a maximum on-resistance of 58 ohms. The device provides an -3dB bandwidth of 180 MHz with typical switching times of 65 ns for turn-on and 80 ns for turn-off. Key electrical characteristics include a charge injection of 6 pC, channel capacitance of 12.7 pF, and a maximum leakage current of 1 µA. It supports a channel-to-channel on-resistance matching of 1.5 ohms and functions across a temperature range of -40°C to +125°C.
Feature Summary
- Single circuit SP8T configuration for signal routing
- Wide operating voltage range from 2.5V to 5.5V
- High bandwidth performance at 180 MHz
- Low power consumption with 1 µA leakage current
Applications
- Signal multiplexing in data acquisition systems
- Audio and video signal routing
- Industrial control signal switching
- Communication equipment interface circuits
Procurement Notes
Verify the specific ordering suffix XTSS16 to confirm the 16-TSSOP package and tape-and-reel packaging format. Ensure compatibility with RoHS3 standards and MSL level 3 moisture sensitivity requirements during storage and handling. Confirm availability status as supply constraints may affect immediate fulfillment.
Selection Notes
Select this component when a single 8:1 multiplexer is required with moderate on-resistance limits. The 16-TSSOP package suits surface-mount applications with limited board space. Consider the 180 MHz bandwidth for high-frequency signal integrity needs. Verify that the 58 ohm maximum Ron meets the system's voltage drop specifications.
Part Context
This part belongs to the RS2251 series of analog switches from Runic Technology. It is distinct from other variants like the RS2252XTQC16 which uses a QFN-16L package. The series focuses on general-purpose signal switching with balanced performance metrics for industrial and consumer electronics.
Replacement Considerations
Direct substitutes must match the SP8T topology, 16-TSSOP package, and similar electrical parameters. Check pinout compatibility before substitution. Alternative packages such as QFN require careful layout review.
